Specification of Letters Patent.

Patented May 22, 1906.

Application filed September 28, 1904. Serial No. 226,309.

To all whom it may concern.-

Be it known that I, JULIUS CH. TOURNIER, a citizen of the United States,residing at Schenectady, in the county of Schenectady and State of NewYork, have invented certain new and useful Improvements in Rosettes, ofwhich the following is a specification.

The present invention relates to insulating ceiling-blocks or rosettesfor protecting joints between branch conductors and main conductors andalso serving as a means of suspension for the branch conductor and thedevices carried thereby.

The object of my invention is to provide a highly-efficient compactdevice of this character wh ch shall be of attractive appearance and oflow cost of manufacture.

In the accompanying drawings, forming a.

part of this specification, Figure 1 is a plan view of a rosetteembodying one formof my invention. Fig. 2 is a longitudinal section online 2 2 of Fig. 1. Fig. 3 is a transverse ,section on line 3 3 of Fig.1, and Fig. 4 is a plan of the base-block.

Where electric conductor-wires are carried across a Wall or ceiling, itis customary to support them in grooves 1, formed near opposite edges ofnarrow moldings 2, which are secured at intervals to the wall orceiling, according to the location of the joists, and over the wires aremovable cap-piece 3 is secured to the molding 2, and in order that myrosette may be connected to the main wires at any point I have desi nedit so that it may be applied to the molding without cutting the latter.

The insulating base-piece 4 is made wide enough to extend across bothgrooves 1 and has side recesses 5 and 6, from which extend in oppositedirections to the top of the base sloping channels or notches 7, intowhich the main wires may be bent, and in these side recesses 5 6 arearranged metallic contact-strips 8 with bent ends 9, adapted to takeunder the bends in the main Wires and binding-screws 10, by which thewires are securely held to the contact-strips 8. The lower side of thebase is provided with a depending central barrier portion 11, havingupwardly-sloping ends 12, which join horizontal end portions 13, andextending diagonally across the depending central portion 11 is a groove14 for the passage of the branch wires. At opposite ends of the groove14 are formed depressions 15 and 16, which connect at 17 with therespective side recesses 5 and 6. The contact-strips 8 have attachingportions from portions of the contact-strips 8 are arranged to engagethe bottomsof the side recesses 5 and 6 and are secured in fixedpositions by screws 20, arranged in countersunk holes 21 near the endsof the central barrier portion 1 1.

The base-block 4 is not attached to the molding 2, but is held inposition by the rectangular inclosing shell 22, having a widthcorresponding to the width of the molding and provided in the center ofits closed end with an aperture 23, through which the branchconductor-wires may pass. The aperture 23 is countersunk to receive theusual knot in the conductonwires. The inner surface of the closed end isformed in two planes with inclines connecting them to form a seat forthe base-block 4 to rest upon when drawn down away from the molding. Theshell 22 is secured to the molding 2 by screws 24 passing through holesnear the ends and entering the material of the molding 2. In order toprotect these screws from coming into contact with a live wire, theinner end Walls are provided with semicylindrical enlargements 25 andthe base-block 4 with corresponding end grooves 26, which serve tocenter the block relatively to the shell.

It will be observed that the base-block is not subjected to strainseither by screws securing it in place or by the weight of the branchwires and devices attached thereto and accordingly may be made verylight and compact and thereby permitting an inclosing shell ofcorrespondingly small dimensions to .be used.

I do not desire to restrict myself to the particular form or arrangementof parts herein described and shown, since it is apparent that they maybe changed and modified without departing from my invention.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is"

1. In a rosette for electrical conductors, the combination of abase-block provided at its upper part with side recesses and at itslower part with side depressions which communicate with said recesses, acontact-plate located in the recesses and'depressions on each side ofthe block, and provided at both ends with binding-screws and aninclosing shell.

2. In a rosette for electrical conductors, the combination of aninsulating base-block having in its upper part central side recesses andin its lower part diagonally-disposed side depressions eachcommunicating with a recess, a contact-plate provided With bindingscrewslocated in each set of connecting recesses and depressions, and .a shellinclosing said base.

3. In a rosette for electrical conductors, the combination of aninsulating-base having line-connectors on opposite sides thereof and acentral transverse barrier on its lower surface, and an inclosing shellloosely supporting said base.

4. In a rosette for electrical conductors, the combination of aninsulating-base having a central transverse barrier on its lowersurface, contact-plates secured to the opposite sides of said base andhaving binding-screws in their upper ends for engaging the line-Wiresand in their lower ends for engaging the branch Wires, and an inclosingshell provided with an internal seat for loosely supporting said base.

5. In a rosette for electrical conductors, the combination of aninsulating-base having a central transverse barrier provided with adiagonal groove, binding-posts for the linewires located on oppositesides of said base near its upper surface, binding-posts for the branchwires connected thereto and located near the lower surface of said blockin line with said groove, and an inclosing shell progided with a seatfor loosely supporting said ase.

In witness whereof I have hereunto set my hand this 27th day ofSeptember, 1904.
